FOREWORD

The American National Standards Committee B107, Socket Wrenches and Drives, under spon- sorship of The American Society of Mechanical Engineers (ASME), was reorganized on June 28, 1967, as an ASME Standards Committee, and its title was changed to Hand Tools and Accessories. In 1996, its scope was expanded to include safety considerations.

In 1999, ASME initiated a project to consolidate hand tool standards by category of tool. The initial implementation included distinct standards within a single publication bearing a three- digit number corresponding to the responsible B107 subcommittee. It was intended that subse- quent revisions would integrate the component standards, resulting in a more traditional docu- ment. This revision redefines types and classes of screwdrivers and screwdriver bits; designations are provided in Nonmandatory Appendix A.

The purposes of this Standard are to define dimensional, performance, and safety requirements specifically applicable to screwdrivers and screwdriver bits, to specify test and gaging methods to evaluate performance relating to the defined requirements, and to indicate limitations of safe use.

This Standard may be used as a guide by state authorities or other regulatory bodies in the formulation of laws or regulations. It is also intended for voluntary use by establishments that use or manufacture the tools covered.

ASME B107.600-2008 superseded, replaced, and rendered obsolete the following standards: B107.15, Flat Tip Screwdrivers

B107.26, Screwdriver Bits, Hand Driven B107.30, Cross Tip Screwdrivers B107.31, Screwdrivers, Cross Tip Gaging

Members of the Hand Tools Institute (HTI), Screwdriver Standards Committee, through their knowledge and hard work, have been major contributors to the development of B107 standards. Their active efforts in the promotion of these standards are acknowledged and appreciated.

Previously, the dimensional specifications for flat tip screwdrivers were derived from manufac- turers’ catalogs. Over a period of several years, members of the B107 Committee reviewed and reevaluated the dimensions against the corresponding standards produced by the ASME B18 Committee for the Standardization of Bolts, Nuts, Rivets, Screws, Washers, and Similar Fasteners. Members of the HTI Screwdriver Standards Committee sourced related fasteners to validate that they are being produced in conformance with the applicable standards. These changes will provide for optimum fit when using flat tip screwdrivers built to conform to this Standard.

Suggestions for improvement of this Standard will be welcomed. They should be sent to The American Society of Mechanical Engineers, Secretary, B107 Standards Committee, Two Park Avenue, New York, NY 10016-5990.

This revision was approved as an American National Standard on June 29, 2016.

CORRESPONDENCE WITH THE B107 COMMITTEE

General. ASME Standards are developed and maintained with the intent to represent the consensus of concerned interests. As such, users of this Standard may interact with the Committee by requesting interpretations, proposing revisions or a Case, and attending Committee meetings. Correspondence should be addressed to:

Secretary, B107 Standards Committee

The American Society of Mechanical Engineers Two Park Avenue

New York, NY 10016-5990

https://go.asme.org/Inquiry

Proposing Revisions. Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Standard. Approved revisions will be published periodically.

The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation.

Proposing a Case. Cases may be issued for the purpose of providing alternative rules when justified, to permit early implementation of an approved revision when the need is urgent, or to provide rules not covered by existing provisions. Cases are effective immediately upon ASME approval and shall be posted on the ASME Committee Web page.

Requests for Cases shall provide a Statement of Need and Background Information. The request should identify the Standard and the paragraph, figure, or table number(s), and be written as a Question and Reply in the same format as existing Cases. Requests for Cases should also indicate the applicable edition(s) of the Standard to which the proposed Case applies.

Interpretations. Upon request, the B107 Standards Committee will render an interpretation of any requirement of the Standard. Interpretations can only be rendered in response to a written request sent to the Secretary of the B107 Standards Committee at go.asme.org/Inquiry.

The request for an interpretation should be clear and unambiguous. It is further recommended that the inquirer submit his/her request in the following format:

Subject: Cite the applicable paragraph number(s) and the topic of the inquiry.

Edition: Cite the applicable edition of the Standard for which the interpretation is being requested.

Question: Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. The inquirer may also include any plans or drawings that are necessary to explain the question; however, they should not contain proprietary names or information.

Requests that are not in this format may be rewritten in the appropriate format by the Committee prior to being answered, which may inadvertently change the intent of the original request.

ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, persons aggrieved by an interpretation may appeal to the cognizant ASME Committee or Subcommittee. ASME does not “approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity. Attending Committee Meetings. The B107 Standards Committee regularly holds meetings and/or telephone conferences that are open to the public. Persons wishing to attend any meeting and/or telephone conference should contact the Secretary of the B107 Standards Committee.

Future Committee meeting dates and locations can be found on the Committee Page at go.asme.org/B107committee.
